Inspired by writer/director John Carney's life and love for music, Sing Street tells the story of a 14-year-old named Cosmo growing up in 80's Dublin who must break free of a home strained by his parents' relationship and money troubles, deal with his drop-out older brother's antics, and survive a new public school where the kids are rough and the brothers are tougher. Cosmo writes a song, forms a scrappy band with some school mates, writes more songs, and shoots some wicked music videos. How to shoot pop videos in a recession ridden country? Beg, borrow and steal. And steal. But when he realizes he can't save his family, he must make a family of his own.
